014 and 010 blocks are good.

look in the timing chain area on the block and you will see no numbers or 010 or 020 or both 010 and 020,the blocks marked with a 010 and 020 together are the best blocks,because they have a higher nickel content for durability and more tin for a better pour during the casting prosess.hope that might help you out.

That's the number of the most common 350 block. Made from late 60's through late 70's. The 014 was about the same casting.

-Could be 2 or 4 bolt
-Look for the 010 and 020 under the T-cover as stated above. Many had neither marking, quite a few have the 010 and hardly any had both.
-Also, look at the oil galley plugs. Many of the 2 bolts had pressed in plugs above the oil filter and on the back of the driver side deck by the distributor. There's nothing technically wrong with them aside from being a pain to clean or pull and tap for a bigger plug.

I used a 397010 with the 010 under the T-cover 2 bolt converted to splayed 4 bolt this year. Have a 4 bolt 397010 w/010 as a backup and a 'no marking' 397010 2 bolt as a spare to the backup.

Go to www.mortec.com for casting number info. Sounds like a one-piece rear seal block to me. My question was the casting number is upside down, not facing forwards in the conventional way. Yes, it is a 4-bolt main 350 hi-nickel block(I already knew that much). Is this an older 'Vette block?

I checked on your casting number. '80-'85 2 or 4-bolt main. 2-piece rear main. Sounds like a good start to me.

I think the dipstick will be on the opposite side as normal on a 207 block. Otherwise I think they are good.
